✦ Synopsis


The vegetation eaten by animals on large areas of several continents is deficient in phosphate and deleterious effects on physiology, particularly reproduction, ensue. Recordson bone chewing behaviour by both pastoral and wild game animals extend over two centuries. In laboratory investigation of this apt behaviour it has been shown that the appetite for bones is innate andspeciJc andcuedpredominantly by olfactory stimuli. It is suppressed by rapidly increasing the plasma phosphate concentration to normalbut not injuenced by increasing the phosphate concentration in cerebrospinaljuid. The central organization of this genetically programmed behaviour appears to direr from systems subserving thirst and sodium appetite.
